Tea naturally keeps fresh best in tight-fitting canisters and in sealed tin or lead packages, but it deteriorates with age no matter how packed. A retailer who is jealous' of his reputation should sell no tea of any kind—package or otherwise—that is more, than six to nine months old.
Tea Analysis and Its Use as a Beverage.
The most important components of the tea-leaf of commerce are (1) Theine, the chief stimulating principle, usually placed by analysis at from 2% to (2) the oil and resinous ingredients, which furnish the flavor and aroma of the liquid, and (3) the tannin and gummy substances, which give it "body" and strength. There is, in addition, a small quantity of essential oil, which slightly increases the stimulating properties.
Chemical analysis shows also a large percentage-40% to 60%—of protein, cel lulose, fibre, etc.—but nearly all of this is found in the residue, the "tea-leaves," left after making the liquid. The greater part of the tannin, which averages from 12% to 18%, meets the same fate if the tea is fresh made.
To enjoy the best qualities of any variety—and also the best physiological effect— tea drinkers should bear in mind that, (1) the water used must be both fresh and boiling; (2) the pot in which the infusion is made must be kept hot, but not boiling, for from three to five minutes after pouring in ; and (3) the tea must not stand longer than three to five minutes before drinking.
If the water used is not fresh—i. e., if it has been standing long or been pre viously boiled—the tea will be flat in flavor. If it is not actually boiling at the time of pouring on the leaves, the result will be a rough, raw taste. A china or earthen pot is better than a metal one. A pot warmed before putting in the dry leaves, is better than a cold one.
The fresh-brewed liquid (after a three to five minutes infusion) contains nearly the total amount of the theine (which corresponds to the caffeine in coffee) and only enough tannin, etc., to give it palatable strength. If it is allowed to stand on the leaves longer than five minutes, its flavor will be injured by the excess of tannin devel oped; if longer than seven minutes, the tannin will not only detract from the flavor, but also tend to render the beverage a detriment to digestion. The brewed tea can, however, be saved for later use, either hot or cold, if poured off the leaves into a china or earthen vessel.
The quantity of leaves required to make good tea depends both on individual tastes and on different varieties. India and Ceylon are generally stronger than China and Japan.
The result is also frequently affected by the water supply—the water in some localities makes much better tea than is possible in others. Some authorities assert that the quality of the water should be considered as a factor when making a blend— that water containing an excessive amount of lime or other mineral matter, requires the stronger, coarser varieties of leaf, and that the delicate types produce their fine flavor and aroma only when the water is "soft." This is disputed by other experts,
who assert that the "best tea" is the best everywhere, though it will display its quali ties to better advantage under favorable conditions.
To make good Iced Tea use from one-quarter to one-third more of the leaf than for tea to be served hot. Prepare the beverage just as carefully, and do not allow it to stand on the leaves for longer than five to seven minutes. Pour the liquid off into another vessel and allow it to cool gradually. It should always be made two or three hours before serving, to give it time to cool gradually. To chill hot tea by setting in the refrigerator or putting ice in it, is to spoil its flavor. When ready to serve, add ice, lemon, sugar, etc., according to taste.
When used as a measure, the word "caddy" now generally signifies any package containing less than a half Chest. A Chinese Chest is equivalent to about 82 pounds or 3/5 of a Pecul (about 139 lbs.). The India and Ceylon Chest contains 90 pounds.
